At initialization time the 'dimm' driver caches a copy of the memory
device's label area and reserves address space for each of the
namespaces defined.
However, as can be seen below, the reservation occurs even when the

Pull rdma updates from Jason Gunthorpe:
"Doug and I are at a conference next week so if another PR is sent I
expect it to only be bug fixes. Parav noted yesterday that there are
some fringe case behavior changes in his work that he would like to
fix, and I see that Intel has a number of rc looking patches for HFI1
they posted yesterday.
Parav is again the biggest contributor by patch count with his ongoing
work to enable container support in the RDMA stack, followed by Leon
doing syzkaller inspired cleanups, though most of the actual fixing
went to RC.
There is one uncomfortable series here fixing the user ABI to actually
work as intended in 32 bit mode. There are lots of notes in the commit
messages, but the basic summary is we don't think there is an actual
32 bit kernel user of drivers/infiniband for several good reasons.
However we are seeing people want to use a 32 bit user space with 64
bit kernel, which didn't completely work today. So in fixing it we
required a 32 bit rxe user to upgrade their userspace. rxe users are
still already quite rare and we think a 32 bit one is non-existing.

When the system is idle it is likely that most files under /proc/PID
will be identical for various processes. Scanning _all_ the PIDs under
/proc is unnecessary and implies that we are thoroughly scanning /proc.
This is _not_ the case because there may be ways userspace can trigger
creation of /proc files that leak addresses but were not present during
a scan. For these two reasons we should exclude all PID directories
under /proc except '1/'
Exclude all /proc/PID except /proc/1.

Currently we are repeatedly calling `uname -m`. This is causing the
script to take a long time to run (more than 10 seconds to parse
/proc/kallsyms). We can use Perl state variables to cache the result of
the first call to `uname -m`. With this change in place the script
scans the whole kernel in under a minute.
Cache machine architecture in state variable.

Currently script has multiple configuration arrays. This is confusing,
evident by the fact that a bunch of the entries are in the wrong place.
We can simplify the code by just having a single array for absolute
paths to skip and a single array for file names to skip wherever they
appear in the scanned directory tree. There are also currently multiple
subroutines to handle the different arrays, we can reduce these to a
single subroutine also.
Simplify the path skipping code.

Currently script parses binary files. Since we are scanning for
readable kernel addresses there is no need to parse binary files. We
can use Perl to check if file is binary and skip parsing it if so.
Do not parse binary files.

Currently script only supports x86_64 and ppc64. It would be nice to be
able to scan 32-bit machines also. We can add support for 32-bit
architectures by modifying how we check for false positives, taking
advantage of the page offset used by the kernel, and using the correct
regular expression.
Support for 32-bit machines is enabled by the observation that the kernel
addresses on 32-bit machines are larger [in value] than the page offset.
We can use this to filter false positives when scanning the kernel for
leaking addresses.
Programmatic determination of the running architecture is not
immediately obvious (current 32-bit machines return various strings from
`uname -m`). We therefore provide a flag to enable scanning of 32-bit
kernels. Also we can check the kernel config file for the offset and if
not found default to 0xc0000000. A command line option to parse in the
page offset is also provided. We do automatically detect architecture
if running on ix86.
Add support for 32-bit kernels. Add a command line option for page
offset.

Currently script uses Perl to get the machine architecture. This can be

Currently script only supports 4 page table levels because of the way
the kernel address regular expression is crafted. We can do better than
this. Using previously added support for kernel configuration options we
can get the number of page table levels defined by
CONFIG_PGTABLE_LEVELS. Using this value a correct regular expression can
be crafted. This only supports 5 page tables on x86_64.

positives against $match, we can convert $match to a hexadecimal value
then check if it lies within the range of vsyscall addresses.

Commit 58eb5b6707 ("pstore: fix crypto dependencies") fixed up the crypto
dependencies but missed the case when no compression is selected.
With CONFIG_PSTORE=y, CONFIG_PSTORE_COMPRESS=n and CONFIG_CRYPTO=m we see
the following link error:
fs/pstore/platform.o: In function `pstore_register':
(.text+0x1b1): undefined reference to `crypto_has_alg'
(.text+0x205): undefined reference to `crypto_alloc_base'
fs/pstore/platform.o: In function `pstore_unregister':
(.text+0x3b0): undefined reference to `crypto_destroy_tfm'
Fix this by checking at compile-time if CONFIG_PSTORE_COMPRESS is enabled.

Pull SELinux updates from Paul Moore:
"A bigger than usual pull request for SELinux, 13 patches (lucky!)
along with a scary looking diffstat.
Although if you look a bit closer, excluding the usual minor
tweaks/fixes, there are really only two significant changes in this
pull request: the addition of proper SELinux access controls for SCTP
and the encapsulation of a lot of internal SELinux state.
The SCTP changes are the result of a multi-month effort (maybe even a
year or longer?) between the SELinux folks and the SCTP folks to add
proper SELinux controls. A special thanks go to Richard for seeing
this through and keeping the effort moving forward.
The state encapsulation work is a bit of janitorial work that came out
of some early work on SELinux namespacing. The question of namespacing
is still an open one, but I believe there is some real value in the
encapsulation work so we've split that out and are now sending that up
to you"

"We didn't have anything to send for v4.16, but we're back with a
little more than usual for v4.17.
Eleven patches in total, most fall into the small fix category, but
there are three non-trivial changes worth calling out:
- the audit entry filter is being removed after deprecating it for
quite a while (years of no one really using it because it turns out
to be not very practical)
- created our own version of "__mutex_owner()" because the locking
folks were upset we were using theirs
- improved our handling of kernel command line parameters to make
them more forgiving
- we fixed auditing of symlink operations
Everything passes the audit-testsuite and as of a few minutes ago it
merges well with your tree"
